Netsanet Gudeta gave the standout performance of the competition, winning with a half marathon world record of 1:06:11 hours in a women-only race. This improved Lornah Kiplagat's eleven-year-old championships record by 14 seconds and marked a personal improvement of over a minute. She led the Ethiopian women (alongside fifth and sixth placers Zeineba Yimer and Meseret Belete) to the team title with a combined time of 3:22:27 hours. The outright world record holder Joyciline Jepkosgei settled for second and her third-placed compatriot Pauline Kaveke Kamulu helped Kenya to second in the team competition. The best performance by a non-African-born runner was by Romania's Ancuţa Bobocel, who set a personal best in 15th place.
In the men's race Kenya's Geoffrey Kipsang Kamworor took his third straight title in 1:00:02 hours (nearly a minute short of his championship record). Bahrain's Abraham Naibei Cheroben claimed the silver medal 20 seconds further back and Aron Kifle was the bronze medallist around half a minute short of the winner. The winning men's team, Ethiopia, contained no medallists but Jemal Yimer, Getaneh Molla and Betesfa Getahun rounded out the top six. The best non-African-born performer was Julien Wanders of Switzerland who managed eighth place in 1:01:03 hours.
A total of 151 men (including 23 teams) finished the distance, with five men failing to finish the distance and three entrants being non-starters. A total of 122 women (including 19 teams) entered and started the race, with 117 finishers. Seven men's and seven women's national records were broken at the competition.
